Alternator is supplying the battery with too high of a voltage, which will damage the battery
overtime.
With 12V systems, a fault is indicated when the voltage detected is between 14.8 – 16.2V.
With 24V systems, a fault is indicated when the voltage detected is between 29.6 – 32.1V.
Alternator is supplying the battery with proper amount of voltage.
With 12V systems, proper amount of voltage is between 13.7 – 15.1V.
With 24V systems, proper amount of voltage is between 27.4 – 30.0V.
To Test Alternator:
Start the engine of the automobile.
Locate the SLI battery on the automobile.
With the engine running, connect the RED battery clamp of the tester to the
positive battery terminal and the BLACK battery clamp to the negative battery
terminal.
The “Alternator Test” will begin with the Battery State being tested, followed by
the test result of the Alternator State and State of Charge being indicated on the
tester.

To Test Battery:
Start with the engine of the automobile being OFF.
Locate the battery to be tested.
With the engine OFF, connect the RED battery clamp of the tester to the positive
battery terminal and the BLACK battery clamp to the negative battery terminal.
The “Battery Test” will begin with the Battery State being tested, followed by the
State of Charge being indicated on the tester.

To Test Battery Being Charged by Battery Charger/Maintainer:
Alternator State
Tests whether the alternator is supplying too much of a voltage to the battery or not.
Battery State
Indicates if the battery is in working condition or not.
Start with the engine of the automobile being OFF.
Make sure the battery charger/maintainer is connected to the battery correctly
and is supplying a charge.
With the engine OFF and the battery charger/maintainer ON, connect the RED
battery clamp of the tester to the positive battery terminal and the BLACK battery
clamp to the negative battery terminal.
The “Battery Being Charged by Batter Charger/Maintainer Test” will begin with the
Battery State being tested, followed by the test result of the Alternator State and
State of Charge being indicated on the tester.
Since the alternator is not involved with this test, a FAULT indication under the
“Alternator State” during this test indicates that the BATTERY IS FULL and the
battery charger/maintainer should be disconnected to prevent the battery being
damaged from overcharging. A GOOD indication under the Alternator state during
this test indicates that the BATTERY IS CHARGING by the battery charger/main-
tainer.

FAU LT
Indicates that the battery is in working condition and supplies a voltage of at least 10V.
If the LED indicator light remains o when the tester is connected to the battery, the battery is
likely dead/defective/not in a working condition.
-
-
GOOD
State of Charge
Indicates an approximation of the battery’s current state of charge.
Indicates that the battery is fully charge.
With 12V systems, battery will be supplying 12.7 – 16.2V.
With 24V systems, battery will be supplying 25.4 – 32.1V.
-
-
-
100%
Indicates that the battery is charged to approximately 80% of its capacity.
With 12V systems, battery will be supplying 12.3 – 13.0V.
With 24V systems, battery will be supplying 24.6 – 25.8V.
-
-
-
80%
Indicates that the battery is charged to approximately 60% of its capacity.
With 12V systems, battery will be supplying 11.8 – 12.6V.
With 24V systems, battery will be supplying 23.6 – 25.0V.
-
-
-
60%
Indicates that the battery is charged to approximately 40% of its capacity.
With 12V systems, battery will be supplying 11.1 – 12.1V.
With 24V systems, battery will be supplying 22.6 – 24.0V.
-
-
-
40%
The battery being tested is supplying less than 10V of power, which usually indicates that the
battery is dead / defective / not in a working condition.
-
None of the LED indictors are ON
The battery being tested is supplying more than 10V of power, however, it is supplying less than
11.1V @ 12V DC or 22.6V @ 24V DC, which indicates its state of charge being below 40%.
-
The battery being tested is supplying more than 10V of power and the alternator is supplying a
good charge to the battery, however, the battery is supplying less than 11.1V @ 12V DC or 22.6V
@ 24V DC, which indicates its state of charge being below 40%.
-
With the engine o, only the Battery State LED indicator is ON
With the engine running, the Alternator State and Battery State LED indicators
are on, but none of the State of Charge LEDs are on.
The alternator is not supplying the battery with any charge, which usually indicates that the
alternator is faulty.
-
With the engine running, the Battery State and State of Charge LED indicators
are on, but none of the Alternator State LED indicator is ON.
